Vedclass · Answer

(C) When the container is placed in a large evacuated chamber,the pressure above the water surface drops significantly. This causes rapid evaporation of the water molecules. Since evaporation is an endothermic process,the latent heat required for vaporization is taken from the remaining water. As the remaining water loses energy,its temperature drops below $0\,^{\circ}C$,causing it to freeze. Thus,a portion of the water vaporizes,and the remaining portion freezes.

If water at $0\,^{\circ}C$ kept in a container with an open mouth is placed in a large evacuated chamber,what will happen?
